What Goes Into Buying a Water Purification System?

As part of our online Lab Products Survey series, we present the results from our recent survey on purchasing a water purification system.

Water is perhaps the most utilized reagent in a laboratory and is often critical for an experiment. As instruments have become more sensitive and applications increasingly complex, the demand for high-purity water has also increased. A few years ago, parts per million (ppm) was a very small level of contamination, but now people are looking for partsper- billion (ppb) or parts-per-trillion (ppt) levels of contamination.

There are eight commonly used methods to purify water: distillation, deionization, reverse osmosis, activated carbon filtration, microporous filtration, ultrafiltration, ultraviolet oxidation and electrodialysis. The National Committee for Clinical Laboratory Standards (NCLS) has specified three types of water: I, II and II, as well as special-purpose water, depending on their use.

Scientific communication researchers see a change in the prevailing mode of scientific communicationthe top-down deficit model to one in which being engaged with the public at some level is just part of what it means to be a scientist.
